EVAPORATOB FOR CARBUBETORS.

Application filed May 5, 1925. SeriaI No. 28,278.

This invention relatesto improvements in the mixturessupplied to the carburetors of 1 engines and in the means for supplying the carburetors withthese mixtures, and it is the principal object of the invention to supply to the carburetor a mixture of air and gas as well as of water vapor or steam in order to increase the explosive function and to supply a'rich'and Well primedmixture.

Another object of the invention is the provision of a means for generating the vapor to be supplied to the air and gas mixture, by means of the heat of the exhaust. 3 A further object of the inv-entionis' the provision of a vapor or steam generator equipped with a controlling and safety valves, and a sifter.

A still further object of theinvention is the provision of a vapor generator including awater tank equipped with means for controlling the supply of heat to the same.

These and other objects and advantages of my invention will become more fully.

known as the description thereof proceeds, and will then be specifically defined in the appended claims.

Inthe accompanying drawing forming a material part of this disclosure:

Fig. 1 is a side elevation of an engine cylinder andcarburetor equipped with the novel vapor generator, constructed according to the present invention. 7

Fig. 2 is a section on line 22 of Figure 1.

Fig. 3 is a section on line 3-8 of Figure-2.

Fig. 4 isan enlarged detail sectional view of the heat supply controlling means, taken on the line 4.-4 of Fig. 1.

An engine cylinder 10 of any well known type, is associated with a carburetorll of any customary construction, intake manifold 12, and exhaust pipe 13- The exhaust pipe 13 has attached to by means of brackets 14 and 15, a. water tank 16 with a filling opening closed by a removable cap 17, and a drain opening closed by a removable cap 18. A water vapor supply pipe 19 leads from the tank 16 to the carburetor and is equipped with a vapor supply controlling valve 20 and a safety valve 21 of any well known'construction and type. A sieve or sifter 22 is provided at the outlet from tank 16 to pipe 19 for retaining the impurities contained in the water and vapor.

, The heat supply from exhaust pipe 13 to tank 16; is controlled by means of a slide 23, having an operating knob 24t and a plurality of longitudinal slots 25' into which slidably engage the fingers26 of a collar 27 secured to a flange116 of'tank 16by rivets 27. so

that the heat supply surface, may be controlled, as desired by adjusting the slide 23 to vary the amount of opening 28 between the slide and the collar 27, soas to change the amount of contacting radiationsurface.

No openings exist for the passage of gases between pipe 13 and tank 16. The-heatis terial of pipe and tank, and. the amount of radiation is controlled by slide 23 which varlesthe amount'of radiation surface.
